dated March 31, 1885.

Application filed June 4, 1884. (No model.)

reference being had to the annexed drawings,

forming part of this specication.

The object of this :invention is to provide a ro jetty in which the wood-work shall be coinpletely protected against the teredo.

In the drawings, Figure 1 is a cross-section of niy improved jetty. Fig. 2 is a partial plan view ofthe saine. Fig. 3 is a side elevation. Figs. 4 and 5 are detail views, and Fig. 6 is a diagram shox'ving a niethod of broadening the base of the structure.

A indicates a wall of concrete inclosed in rnetal plates B, which are bolted to mud-sills C, and supported by braces D and stay-rods E; and F and G are mats and stones for anch oring the sills and preventing any wash along the base of the jetty. The plates .B are made in unif'orni sheets, having iianges c at their upper edges, by which one sheet may be connected to another with a cap-plate, d, and rivets e, passing through said flanges and capplate. The two plates thus connected together' are slightly inclined toward each other froni their base up, and are further connected together by cross-bolts f, passing through the plates Aat suitable distances apart i'roni top to bottom. A shell or section, b, is thus formed, which is then inverted and iilled with concrete A. When the concrete hardens, it will be firmly secured in the shell by the bolt f. Thesection b is then turned to its proper upright position and bolted to the mud-sills C by means of the broad flanges g at the lower ends of said plates, and supported by the braces I), which are bolted both to the sills and to the plates. A single section, b, thus extends from the extreme top ofthe structure to the base or sills O, and each section is thus put down separately, and is secured to its next adjacent section by the fianges t' on the upright edges of the plates, and rivets j, con necting the flanges t' of one section with those of another.

The sills C are arranged parallel with each other at about eight feet apart, and are provided near their ends with pointed uprights to which the stay-rods E are secured after the mats F are put down.

attached to the upper ends of the sections 2),.

and are provided with a tension-adjusting device, m, of well-known construction. stones are placed on the mats t0 Weight them down and hold them in place.

In order to strengthen the jetty against lateral pressure, it is run in a zigzag direction, as shown in Fig. (i, thus giving it practically a broader base without addition of' material. The angle of deiiection to right and left may be varied at will, but a very slight deflection from a right line will greatly strengthen the structure. Vith this construction the entire jetty, except the sills and mats, is made of' metal and stone. The only wood being the sills, which are completely embedded in the mud, there is no part of the structure which can bc injured by t-he tcredo. The nietal plates are to be coated with suitable material or paint, to protect them from oxidation. It is intended that the niats shall extend from fifteen to thirty i'eet outward at each side of the wallrand considerably beyondl the ends of'` the sills, to prevent any possibilit-y of Washing out at the base. The fianges g on the lower ends of the plates Bare to be about The.

The stay-rods are three feet wide at each side of the wall, to

serve as a base to prevent the jetty from settling down too deep in the n1ud.

that I claim is- 1. The combination of the plates riveted together to forni shells. the wall of' concrete inelosed in said shells, the inudsills to which said shells are bolted, and the anchoring mats and stones, substantially as shown and described.

2. The combination ofthe metallic sections formed of plates riveted together at their upper ends and connected together by crossbolts, the filling of concrete, the mud-sills, the braces, the stay-rods, and the mats and stones, substantially as shown and described.

The plates having broad flanges at their lower ends to forni a base to support the same on mud-bottonis, substantially as shown and described.
